Instructions for using of fuel and oil
Fuel
Please use unleaded gasoline. If the engine is mak-
ing a slight knocking noise, it may be using normal
grade fuel and should be replaced.
Notice
Use unleaded gasoline to extend the life of your
spark plugs.
Engine oil
Please use a high-purity, high-
performance fully synthetic
engine oil that meets the SN
level or exceeds this level.
The factory recommends SN
15W-50. [The loss of engine
failure caused by the pur-
chase of our company's fully synthetic oil will affect
the warranty of the vehicle]. The oil viscosity should
be determined according to the air temperature in
the driving area. You can refer to the following figure
to select the appropriate oil viscosity.
Running in
Top speed
For new motorcycles, during the first 1500km run -in
driving, do not make the engine run excessively or
suddenly accelerate, turn suddenly and brake sud-
denly, and do not make its speed in any gear posi-
tion exceed 80% of its maximum speed; Avoid
operating the throttle valve fully open.
Engine speed change
The speed of the engine is not kept constant, but is
changed from time to time, which helps the parts fit.
During the break-in period, it is necessary to apply
proper pressure to the various parts of the engine to
ensure a complete fit. But don't put too much load
on the engine.
Avoid continuous operation at a low speed
Continued operation of the engine at a low speed
(light load) will cause excessive wear of the parts
resulting in a poor fit. As long as it does not exceed
the recommended maximum speed limit, you can
engage each gear to accelerate the engine, but
during the run-in period, the maximum accelerator
cannot be added.
